Fast Batteries

Here are two articles about a recent battery development that could lead to charge rates similar to super-capacitors.

In the fast lane: Conductive electrodes are key to fast-charging batteries: Researchers use mxene to push charging rate limits in energy storage www.sciencedaily.com Can you imagine fully charging your cell phone in just a few seconds? Researchers can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design.

And from New Atlas.

"Ion highway" electrodes drive development of batteries that charge in seconds

A team at Drexel University has used the two-dimensional material MXene to develop a new type of electrode, combining the capacitance of a regular battery with the speed of a supercapacitor, which could lead to devices that recharge in a matter of seconds.
